IDENTIFICATION AND USE OF PROGNOSTIC AND PREDICTIVE MARKERS IN CANCER TREATMENT

摘要

The present invention provides a method of screening for markers useful in predicting the efficacy of a specified cancer that includes: (a) constructing a tissue microarray from a tissue bank comprising multiple tissue samples that are annotated with clinical follow up data; (b) labeling polynucleic acid probes specific for oncogenes or cancer associated genes known to be potential amplicons; (c) performing fluorescent in situ hybridization analysis on the tissue microarray; and (d) correlating the result of the fluorescent in situ hybridization with the clinical follow up data. In addition, the present invention provides a method of treating breast cancer that includes measuring the expression levels or amplification of HTPAP in a patient having breast cancer and then providing a patient having increased levels of HTPAP expression or HTPAP amplification with therapeutic quantities of at least one compound that interferes with the phosphatidic acid phosphatase activity of HTPAP. The present invention also encompasses a method of treating breast cancer that includes screening a breast cancer patient for amplification of the cMYC gene and then treating a patient having amplification of the cMYC gene with therapeutic quantities of a compound that interferes with HER2 signaling.
